Heating and air conditioning system 111
Recirculated air mode
Climatic* (semi-automatic air conditioning system)
In recirculated air mode air is sucked out of the interior of the vehicle
and then fed back into the interior.
Description
The Climatic is a combined cooling and heating system. It makes it
possible to optimally control the air temperature at any season of the
year.
Recirculated air mode prevents polluted air outside the vehicle from
getting into the vehicle, for example when driving through a tunnel or
when standing in a traffic jam.
Description of the Climatic
Switching recirculated air mode on
It is important for your safety and for your driving comfort that the Climatic is oper-
ating properly.

If the cooling system is switched on, the temperature and air humidity drops in the
vehicle. The wellbeing of the occupants of the car is enhanced as a result of this
particularly at high outside temperatures and a high air humidity. The system
prevents the windows misting up during the cold season of the year.

WARNING
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
You should not leave recirculated air mode on over a longer period of time,
as “stale” air may result in fatigue in the driver and occupants, divert your
attention and also cause the windows to mist up. The risk of having an acci-
dent increases. Switch recirculated air mode off as soon as the windows
begin misting up.
It is possible to briefly activate recirculated air mode in order to enhance the
cooling effect ⇒
.
Air at a temperature of about 5°C may flow out of the vents under certain circum-
stances when the cooling system is operating. Lengthy and uneven distribution of
the air flow out of the vents and large differences in temperature, for example when
getting out of the vehicle, can result in chills in sensitive persons.
The air inlet in front of the windscreen must be free of ice, snow or leaves in order
to ensure that the heating and cooling systems operate properly.
After switching on the cooling Condensation from the evaporator of the air condi-
tioning may drip down and form a puddle below the vehicle. This is quite normal
and not an indication of a leak!
